--- Comment #5 from Coleman Kane (ckane@colemankane.org) --- Created attachment 292017 --> https://bugzilla.kernel.org/attachment.cgi?id=292017&action=edit Xorg log from failure case (same 5.9-next kernel)
Xorg.log from trying to run Xorg under kernel that fails to set resolutions properly. The DisplayPort-0 displays at 1024x768, and I can not set the resolution any higher than that from within Xorg (using the enlightenment "screen" settings panel).
You can see from the following line that it boots into 1024x768: [ 38.608] (II) AMDGPU(0): Output DisplayPort-0 using initial mode 1024x768 +0+0
